Thats great news, nice to hear that you are already planing to implement this. Thanks a lot :)
I second that, customizeable keys would be a real help, especially for games like Skyrim, Fallout etc., which have dozens of keys to map actions to. There I usually use the middle mouse button for other things, and it´s really hard to change a setup, which you have come accustomed to over years.
I can understand that you have more important matters to do, as this is a rather special request. Luckily at least NVSE is working without problems, so I will try to find another LAA solution for Fallout. And thanks for your fast and honest answer. I´ll be able to handle a few more game crashes than usual, if it bothers me too much I have to resort to play without the rift :)
Best wishes
